Cracking behavior of segmented-casting joint in steel-UHPC composite bridge deck system
Experiment and numerical simulation
The cracking of the pre-/post-casting UHPC joint in the steel-UHPC composite bridge deck system can lead to continuous tensile damage in the UHPC layer, reducing its ability to stiffen the steel deck. This study aims to clarify the cracking mechanism of the segmented-casting U ...
Tensile behavior of rebar-reinforced coarse aggregate ultra-high performance concrete (R-CA-UHPC) members
Experiments and restrained shrinkage creep effect
In order to investigate load-carrying capacity, ductility and plastic development of orthotropic steel-concrete composite deck used in composite girder cable-stayed bridge, six single-point-loaded simply-supported orthotropic steel-concrete composite decks with varying axial c ...
The short-headed stud connectors play a critical role on the interaction of the orthotropic steel deck (OSD) and the ultra-high performance concrete (UHPC) layer in orthotropic steel-UHPC composite bridge deck. In this paper, the fatigue behavior of these short-headed stud con ...
